Abstract
A method of aiding uplink transmission is disclosed. One method includes a base station downlink transmitting signals to at least a first terminal, the transmitted signals directed and conveying data to at least the first terminal. The method further includes a second terminal eavesdropping the transmitted signals, and measuring a signal quality. The second terminal estimates uplink channel information based on the measured signal quality, for aiding uplink transmission. Based at least in part on the estimated transmission channel, the second terminal transmits uplink signals to the base station.
